Retention policy-based protection of data written to a data store
An illustrative method includes determining that a first data instance stored within a first data store is replicated as a second data instance stored within a second data store, determining that a second retention policy associated with the second data instance stored within the second data store is at least as stringent as a first retention policy associated with the first data instance stored within the first data store, and modifying, based on the determining that the second retention policy is as least as stringent as the first retention policy, the first retention policy to allow for the first data instance to be modified or deleted without the first set of one or more conditions each being satisfied.
1 . A method comprising:

wherein the modifying the second retention policy to be at least as stringent as the first retention policy comprises:
determining, based on a comparison of the first and second retention policies, that the first retention policy specifies that the first data instance cannot be modified or deleted for a greater amount of time than what is specified in the second retention policy, and

detecting, by the data protection system, a write event in which the first data instance is written to the first data store;
issuing, by the data protection system based on the detecting the write event, a command to perform a replication process in which the first data instance is replicated to the second data store;
wherein the determining that the first data instance is replicated as the second data instance is performed based on the issuing the command to perform the replication process.
5 . The method of claim 4 , further comprising creating, by the data protection system based on the command to perform the replication process, the second retention policy for the second data instance.
6 . The method of claim 5 , wherein:
the second data store comprises an object-based bucket; and
the creating the second retention policy comprises creating an object lock for the object-based bucket that specifies the second set of one or more conditions.
7 . The method of claim 1 , wherein the determining that the second retention policy is at least as stringent as the first retention policy comprises setting the second retention policy to be at least as stringent as the first retention policy.
8 . The method of claim 1 , wherein the modifying the first retention policy comprises transmitting an update command to a data store that stores data representative of the first retention policy, the update command configured to update the data representative of the first retention policy.
9 . The method of claim 1 , wherein:
the first data store comprises a file-based data store; and
the second data store comprises an object-based data store.
10 . The method of claim 1 , wherein the first data store and the second data store are included in a single storage system.
11 . The method of claim 1 , wherein the first data store is included in a first storage system and the second data store is included in a second storage system remote from and communicatively coupled to the first storage system by way of a network.
12 . The method of claim 1 , wherein the data protection system is implemented by a storage system associated with the first data store.
13 . The method of claim 1 , wherein the data protection system is implemented by a storage system associated with the second data store.
14 . The method of claim 1 , wherein the data protection system is implemented by a cloud-based monitoring system communicatively coupled to the first data store and the second data store by way of a network.
15 . A system comprising:
a memory storing instructions; and
one or more processors communicatively coupled to the memory and configured to execute the instructions to perform a process comprising:
determining that first data instance stored within a first data store is replicated as a second data instance stored within a second data store;
determining that a second retention policy associated with the second data instance stored within the second data store is at least as stringent as a first retention policy associated with the first data instance stored within the first data store, the first retention policy specifying a first set of one or more conditions that each have to be satisfied for the first data instance to be modified or deleted from the first data store and the second retention policy specifying a second set of one or more conditions that each have to be satisfied for the second data instance to be modified or deleted from the second data store; and
modifying, based on the determining that the second retention policy is as least as stringent as the first retention policy, the first retention policy to allow for the first data instance to be modified or deleted without the first set of one or more conditions each being satisfied;
wherein when the second retention policy is already created before the first data instance is replicated as the second data instance, the process further comprises modifying the second retention policy to be at least as stringent as the first retention policy; and
